Melbourne Lawn Care Guide

The Melbourne Lawn Care Calendar

A month-by-month guide to mowing, fertilising, aeration and weed control — tuned for Melbourne's climate and the Buffalo, Kikuyu and Couch lawns most common across the northern and western suburbs.

Know your grass first

Buffalo (Sir Walter, Palmetto)

Soft-leaf, shade-tolerant. Mow 40–50mm in summer. Sensitive to broadleaf herbicides — always check the label.

Kikuyu

Fast-growing, hardy. Mow 25–40mm. Handles heavy traffic; needs regular edging to keep it out of garden beds.

Couch / Ryegrass blends

Fine leaf, sun-loving. Mow 20–30mm. Goes dormant/brown in cold Melbourne winters — that's normal.

Month-by-month calendar

January

Peak summer

Mowing: Buffalo 40–50mm · Kikuyu 30–40mm

Focus: Deep, infrequent watering (early morning) to build root depth.

  • Never scalp — long blades shade soil and reduce moisture loss.
  • Skip fertiliser on stressed, dry lawns; wait for a cooler run.
  • Sharpen mower blades — torn tips brown out fast in the heat.

February

Late summer

Mowing: Buffalo 40–50mm · Kikuyu 30–40mm

Focus: Spot-treat summer weeds (paspalum, summer grass) before they seed.

  • Water 2–3× per week, deeply, if under no restrictions.
  • Top-dress bare patches with a fine sandy loam.

March

Early autumn

Mowing: Buffalo 40mm · Kikuyu 30mm

Focus: Autumn fertilise — slow-release NPK to rebuild reserves before winter.

  • Aerate compacted areas (high-traffic paths, kids' play zones).
  • Overseed thin cool-season lawns (rye/fescue blends) as nights cool.

April

Mid autumn

Mowing: Raise 5mm as growth slows

Focus: Broadleaf weed control — bindii, clover, capeweed germinate now.

  • Selective herbicide safe for Buffalo (check for 'Sir Walter safe').
  • Clear fallen leaves weekly to prevent yellow patches.

May

Late autumn

Mowing: Buffalo 45–55mm · Kikuyu 35–45mm

Focus: Last mow of the season is usually late May — leave it slightly longer.

  • Apply wetting agent to combat winter hydrophobic soils.
  • Final feed with a low-N winter fertiliser if lawn still growing.

June

Early winter

Mowing: Only as needed — leave taller for warmth.

Focus: Minimise foot traffic on frost-affected lawn.

  • Do NOT fertilise warm-season grasses (Buffalo, Kikuyu, Couch) — they're dormant.
  • Rake leaves and debris to let light reach the crown.

July

Mid winter

Mowing: Rarely needed

Focus: Plan spring — book aeration, top-dressing and renovation.

  • Sharpen or replace mower blades before spring flush.
  • Treat winter weeds (Poa annua, oxalis) with a selective herbicide.

August

Late winter

Mowing: First light cut as growth returns

Focus: Pre-emergent weed control before summer weeds germinate.

  • Light scarify to remove winter thatch on Kikuyu and Couch.
  • Test soil pH — Melbourne lawns often benefit from lime.

September

Early spring

Mowing: Buffalo 35–45mm · Kikuyu 25–35mm

Focus: Spring fertilise — balanced NPK to kick-start growth.

  • Aerate compacted lawns; top-dress uneven areas with sandy loam.
  • Deep water 1–2× per week as temperatures climb.

October

Mid spring

Mowing: Weekly cuts, drop height gradually

Focus: Repair winter damage — patch, overseed (cool-season) or plug (warm-season).

  • Follow-up fertilise 4–6 weeks after spring feed.
  • Watch for lawn grubs — check by pulling a small patch after warm rain.

November

Late spring

Mowing: Buffalo 40mm · Kikuyu 30mm

Focus: Establish deep-watering rhythm before summer restrictions kick in.

  • Mulch clippings back into the lawn to return nitrogen.
  • Spot-treat any remaining broadleaf weeds while they're actively growing.

December

Early summer

Mowing: Buffalo 40–50mm · Kikuyu 30–40mm

Focus: Raise blade height going into peak heat — longer leaf = deeper roots.

  • Water early morning to reduce evaporation and fungal risk.
  • Skip fertiliser during heatwaves; wait for a milder week.
